1 Claim.

This invention relates to improvements in the paper manufacturing art and is directed more particularly to improvements in the method of manufacturing papers for decorative purposes and the products thereof.

The principal objects of the invention are directed to the provision of a method of making decorative paper which is of novel form so as to be adapted for general decorative purposes. Various novel features and advantages of the invention will be more fully hereinafter referred to in connection with the following description of the present preferred form of the invention and for purposes of disclosure reference will be made to the accompanying drawing wherein;

Fig. 1 is a plan view of a portion of a sheet of paper having the novel features of the invention incorporated therein.

Fig. 2 is a sectional view of the sheet shown in Fig. 1 taken on the line indicated by the numeral 2. I v

Fig. 3 is a portion of a streamer showing a modifled form of the invention, and

Fig. 4 is a sectional elevational view showing superposed strips or webs which are fluted.

Referring now to the drawing in detail the method of the invention will be more fully described.

In Fig. 1 there is represented a portion of a sheet of crepe paper embodying the novel featuies of the invention. This has spaced apart longitudinal extending portions 4, which are creped transversely. Intermediate fluted portions 6 are provided with alternate ridges and grooves disposed transversely between the non-' fluted creped portions 4.

In carrying out the invention it is desirable to employ crepe paper and to form the flutes or alternate grooves and ridges so that they extend generally in the direction of the creping. The alternate ridges '7 and grooves 9 may be formed in the paper, by passing the same between coacting toothed members such as gears. These may exert more or less pressure and in that way provide the grooves shown.

According to the preferred form of the invention a sheet or web of paper may be provided with creping which extends in one direction such as transversely thereof, while suitable rolls may provide the alternate grooves and ridges which terminate in spaced relation so as to form the creped non-grooved and the relatively less creped and grooved sections alternately arranged, with the grooves running in the direction of the crep- As stated, the paper sheet or a strip is extensible and elastic longitudinally thereof, while at the same time certain sections thereof are not only ornamented by the grooves, but these at the same time provide a fullness so that the paper is easily go and readily manipulated.

Fig. 3 shows a modified form of the invention in which there is employed one or more strips 2 of crepe paper or the like wherein the creping extends transversely thereof. According to the 5;

method of the invention a single sheet or strip of crepe paper may be run through coacting toothed members such as gears which act on opposite side edges thereof or two or more of such creped strips are run through gears simul- 7 taneously and in superposed relation.

By employing the crepe paper mentioned and which is more or less flexible, it is distorted more or less by the ridges and its grooves so that its edges are flexible and there is a fullness at the sides of the strip as compared with the central portion thereof. The central portion of the strip is stretchable to some extent and more or less elastic because the strip is creped while the longitudinal edges are less elastic but are quite flexible a support while the edges are sufficiently flexible to assume the spiral formation.

As stated, it is desirable in some cases to superpose two or more strips as shown in Fig. 4 and to provide the fluted edges. The fluting operation on the marginal edges of superposed strips tends to unite the edges so that the plurality of strips appear as a unitary strip consisting of one or more colors if this is desired.

It is often desirable to provide a streamer with difierent colors on opposite sides thereof and which is not possible ordinarily without pasting strips together. According to this invention it is possible to secure separate strips together which may be of different color to provide a unitary strip 1 .having different colors on its opposite sides. Altogether the streamer of the invention is well adapted for decorating purposes in general because it is not only flexible, but is sufiiciently stretchable so that it may be hung in various central or stretchable portion of the strip acts as M ways without destroying or injuring the artistic appearance thereof.

The strip, of course, may be of various widths and the grooves and ridges may extend inwardly from the marginalaedges to any desired depth so as to leave a central longitudinal uncorrugated portion of a desired width which extends longitudinally of the strip. The central creped pore tion is important because the strip by being formed of crepe paper may be made relatively stretchable and elastic-- throughout the central zone as compared with the fulled marginal edges.

The central longitudinal crepe zone acts as a supcreped paper is more or less stretchable so that i it may be offset or distorted without injury thereto.

The non-grooved portions and grooved portions arranged as they are provide a decorative effect which is desirable. At the same time the paper whether in sheet or strip form is very flexible so that it may be folded, bent, curled and otherwise manipulated around and upon objects to create ornamental efiects.

It may be said that the creping. of the paper causes the paper to be more or less firm and elas- .tic, while the grooves provided therein provide a fullness in certain parts thereof. Since the groove portions are separated from one another. the grooving does not destroy the desired stretchability of the paper, but does enhance the appearance thereof and provides a fullness or flufiiness, wherebythe paper is adapted for decorative purposes and as a whole is not likely to be injured in its manipulation.

Having described the invention in the form at present preferred, what it is desired to claim and secure'by LettersPatent of the United States is:

The method of producing paper adapted for ornamental purposes which consists in, fluting the opposite longitudinal sides only of superposed strips of crepe paper to provide strips having relatively fiat central non-fluted sections and flexible distorted edge portions, the said crepe paper having the creping extending transversely thereof and said fluted sections comprising alternate ridges and grooves extending in parallelism with said creping, the grooves and ridges of one strip interfitting with the grooves and ridges of the strip on which it is superposed whereby the relatively fiat central non-fluted sections of the strips are in close adjacency.
